Proac Ribbon Tweeters Damaged

Hi all - this is my first submission, so looking forward to your responses...

I own 2.5 year old Proac D48 R speakers, powered by a Parasound Halo A21 amp (about 8 years old). When listening the other day I thought the speakers sounded dull, muddy. It appears both of my ribbon tweeters have gone out and I am at a loss to understand why.  The amp is certainly not under powered to cause clipping damage and I never play my unit abnormally loud  - maybe 1/4 to 1/3 total volume.

As you can imagine, my repair/driver replacement will not be covered by warranty as this is not considered a manufacturer defect. I am told the tweeters run $399 per.

Worst thing I can do is have these repaired and then have it happen again. HELP!

You may want to check for any DC offset at the amp speaker outputs.
Wondering, are the ribbon tweeters fuse protected? 
My MG 3.5’s have the ribbons fused. Additionally as others have mentioned, the ribbons are  fragile  and can be damaged by excessive air bursts from external sources. Could it be that someone has vacuumed cleaned the speakers?
